Broken tooth extraction in children can be treated by either self-resorption or root extraction, depending on the specific fracture of the root.
1. If the root breakage occurs when a child has a baby tooth extracted, when the broken root is closer to the permanent tooth germ and the broken root is shorter; and when there is a possibility of damaging the permanent tooth germ by continuing extraction, the root can be temporarily not extracted, and the root can be extracted after the broken root has surfaced, or can be resorbed by the child himself/herself.
2. If the root breakage occurs during the extraction of permanent teeth in children, or the root breakage of milk teeth is relatively shallow, or the root breakage is accompanied by chronic apical inflammation, the root breakage can be continued to avoid affecting the restoration of the teeth in the later stage, the normal eruption of the permanent teeth, or the spread of inflammation at the apical area of the root, or the symptoms such as pain.
